Welcome to the forum!We do not pay much attention to our grumpy old time-traveling septuagenarian except to have a laugh.

There is LOTS to consider when deciding whether a car is suitable for biodiesel or not. There are a LOT of unknowns about using biodiesel in these later diesels that people just make wild guesses about without any real knowledge what they are talking about.

If I had enough money to buy a Peugeot 3008 diesel hybrid I would be very reluctant to run biodiesel in it.However, if I were a squillionaire, I would buy one and run it on B100 just to see what happened.

Is it true that most pre 2005 cars can run on B100 without problems? If so, what's the most efficient car that can definitely run on it? Or at least a good one?

I had read that the Citroen Xsara is good but the secondhand ones that are 2004 and earlier all seem to have quite high mileage on them. I'm in the UK, by the way, so there are some differences in the makes and models available over here compared to the US.

Hi! I have the same question about a Citroen Jumpy. In Australia I have been making and driving biodiesel since 1999 on Nissan Patrol, Toyota LC, Dozer, Tractor, generators, pumps without any worries. In France I have a Jumpy 2010 obviously more sophisticated engine with lots of things that doensn't exist on my other older engines. So far I never put anything else than standard petro diesel in it. I would be very careful to put biodiesel in it.
